Interior lighting

12V switched light located in the center of the popup hatch
(provides light inside the bow when closed, and lights up the
entire front deck when hatch is open at night

12V switched light located on the vertical part of the inside
of the anchor box. This provides cabin light all the way up in
the nose of the bow for dealing with the deep cycle batteries
mounted under the bunks up in the bow of the boat

For low intensity interior night lighting when sailing or
just hanging, we use 4 separate red lamps (switched 2 and 2).
These red lamps are just automotive marker lights like you would
find at Pep Boys. They each contain two small bulbs. One pair
of the red lamps has a two-speed switch to cut the brightness
in half (this gives you low level red light and really low level
red light). This is really excellent for preserving your night
vision. With just thirty seconds of white light, your night vision
is shot for fifteen minutes to a half hour depending upon the
exposure to white light. I happen to do a lot of night sailing
(as a percentage of the time I spend on the water).
